Lithium-ion batteries (LIBs) have become the cornerstone of portable electronics, electric vehicles, and alternative energy economies due to their long lifespan, good power storage performance, high energy density, and high operating voltage
The abundance of silicon in the earth's crust is second only to oxygen
Inspired by sphalerite, a research team from Japan's Advanced Institute of Science and Technology proposed a rational design for the preparation of β-SiC-based anode materials at lower temperatures.
Three-dimensional intermetallic structure in the sphalerite system that easily accommodates lithium ions in their interstitial sites
The team designed a two-step synthesis process to prepare β-SiC-based anode materials: the first step is to form silicon nanoparticles in a polydopamine matrix; the second step is to convert them into β-SiC in a nitrogen-doped carbon matrix A special variant of SiC nanoparticles
The research team used the obtained material for battery configuration and performed electrochemical screening
Using this β-SiC-based composite material as the negative electrode material was successfully applied to the full cell (commercial LiCoO2 as the positive electrode)
